I'm a little embarrassed to post this photo but I'm sharing for advice on if anyone has experienced anything similar. I've noticed my 22month olds teeth this morning are discoloured at the bottom. It looks like a yellow plaque that won't come off with brushing. She's been unwell recently with a few admissions, full dose inhalers and antibiotics and although we have brushed teeth twice a day since she was about 6 months, there have been times we haven't been able to get into her mouth but only when poorly and wondered if these may have contributed to it. She is under a dentist so I'll give them a call on Monday to see if there's anything they can do or advise us on doing. Looking for reassurance it's something we can get on top of and hopefully rid of!
